Title: Locking/unlocking device of door body
Inventor: KAMIMURA KEIICHI
IPC: E05B83/18
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a miniaturized locking/unlocking device or a door body, by which the pulling-in motion from the half-latch condition to the full-latch condition and the unlocking motion of the door body can be operated by one shared driving source. SOLUTION: A drive cam 12 is supported by a pivot 7 used in common for a latch 8 engaging with a striker 4 fixing a door to close it. When an electric motor is driven and a rotary body 15 is moved circularly, a link 14 converts the circular motion of the rotary body 15 to the swinging motion of the cam 12. The cam 12 retracts the latch 8 positioned in the half-latch position to the full-latch position in the swinging movement through the second ratchet 17 and unfix the latch 8 positioned at the full-latch position by pushing out the first ratchet 11 through a fixing pin 11b. This link 14 is set so that the latch 8 is positioned at the full-latch position when the rotary body 15 has reached the position Y1 close to the upper dead point Y0 .

Title: Scanning probe microscope
Inventor: UMEKI TAKESHI
IPC: G01N37/00
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a scanning probe microscope capable of performing the positioning of a probe due to coarse movement accurately and easily for a short time. SOLUTION: When a probe 7 is coarsely moved to a sample 8, the application of voltage from a power source circuit 42 to annular electrodes 41a, 41b is stopped. Thereby, the viscosity of an electric viscous fluid 40 lowers instantaneously and a cylindrical movable part 6 is viscously connected to a tubular support part 3 by the electric viscous fluid 40. Therefore, the cylindrical movable part 6 becomes possible to drive by a voice coil motor and the probe 7 can be coarsely moved to the sample 8. When the probe 7 is coarsely moved to a predetermined position, the voice coil motor is stopped and voltage is applied to the annular electrodes 41a, 41b from the power supply circuit 42. Thereby, the viscosity of the electric viscous fluid 40 rises instantaneously and the cylindrical movable part 6 is fixed to the tubular support part 3.

Title: I2l semiconductor device
Inventor: MURAMATSU AKIRA
IPC: H03K19/091
Filed: 1978-12-27
Abstract: PURPOSE:To improve injection efficiency without decreasing withstanding voltage between a collector and an emitter by maintaining impurity concentration in the base region of a vertical type transistor low on the emitter region side and high on the collector region side. CONSTITUTION:On the surface of a p-type silicon substrate 10, an n<+>-region is formed by diffusing phosphorus to high concentration and then an n-type silicon epitaxial layer 12 of low concentration is grown making the n<+>-region into a buried layer 11. Next, a p<->-diffusion layer 13 is formed on the surface of the n<->-epitaxial layer 12, and diffusing acceptor into the layer to high concentration, p-diffusion layers 14 and 15 are formed. Again diffusing donor into the p-diffusion layer 14 to high concentration, n<+>-diffusion layers 16a and 16b for a collector are formed and thus the I<2>L of a vertical type NPN transistor is formed. By so making low the impurity concentration of a base region contacting the n<+>-emitter 11, high injection efficiency is obtained and also high withstanding voltage can be secured, because the concentration at the collector-base junction is high.

Title: Focus error detector
Inventor: AIKO HIDEKI
IPC: G02B7/28
Filed: 1986-07-08
Abstract: PURPOSE:To ensure the stable detection of focus error signal in a simple constitution by forming two semicircular light spots on a 4-split optical detector and securing the rubbing actions of an element of a reflecting optical system to the two guide plane of an optical system base. CONSTITUTION:A guide plane M of an installing guide 21 is provided to an optical system base 9 together with a guide plane N (utilizing an upper plane of the base 9) of the base 9. Thus the two planes approximately vertical to a level difference plane formed by reflecting planes E and F can slide toward K among those planes of a reflecting optical element 6. A focusing luminous flux is divided into two spaces by the element 6. These two special parts are reflected approximately in the same direction with approximately same quantity of light. As a result, two congruent semicircular light spots are formed on a 4-split optical detector 7. The detector 7 performs the position control within a light receiving plan so that the uniform light is received in four light receiving areas. Thus the focus error signal obtained by a differential amplifier 8 is set at zero.

Title: Greens-planting work for sloped hard ground surface
Inventor: TAKINO TADAMORI
IPC: E02D17/20
Filed: 1984-07-30
Abstract: PURPOSE:To prevent the decaying of plant roots by a method in which deep trenches are formed in the direction of crossing the slope of hard ground by high-pressure water jet in such a way as to enable soil for vegetation which is placed on the trenches to be cut into the hard ground readily. CONSTITUTION:Deep trenches 2 along the traverse direction of the slope 1 of hard ground are formed at given intervals in the direction of crossing the slope 1 by high-pressure water jet. A vegetation material 2 composed of soil, fertilizer, water, seeds, fibrous material, tackifier, etc., is placed on the slope 1. The degradation of the ground can be prevented and the trenching work of the ground can be made with very good efficiency because of the use of high-pressure water jet in the formation of the trenches 2 without causing any damage to the surrounding ground. The retaining of rain water can be well attained and also the permeation of rain water into the ground can be promoted due to the presence of the trenches 2. The decaying of plant roots can thus be prevented.

Abstract: PURPOSE:To reduce noises in detuning, by providing a limiter circuit to an AM stereophonic difference signal amplifier. CONSTITUTION:An AM stereophonic broadcast wave is received by an antenna 1 and applied to an envelope detecting circuit 6 through a high-frequency amplifying circuit 2, a mixing circuit 3 and an intermediate-frequency amplifying circuit 5 to obtain a sum signal L+R. Part of the output of the intermediate- frequency amplifying circuit 5 is passed through a limiter circuit 7, a frequency detecting circuit 8, an integral circuit 9, and a low-frequency amplifying circuit 10 to obtain a signal L-R, and both the signals are converted into signals L and R through an inverting amplifier 11 and adders 12 and 13. When a stereophonic broadcast is received and complete tuning is achieved, an AND circuit 18 generated a high-level output by the outputs of a tuning-band detecting circuit 15, a carrier detecting circuit 16, and a stereophonic pilot signal detecting circuit 17, and the transistor (TR)Q1 of a stereophonic/monaural switching circuit 20 turns off. In a detuning state, the TRQ1 turns on to generate a monaural output, but the output of the amplifier 10 is decreased by a limiter 23, reducing noises in switching.

CONSTITUTION:For example, an anti-fouling agent selected from aldehydeamines, aldehyde ammonias, dithiocarbamates, guanidines, thiazoles, imidazoles or thiurams is dispersed in a polymerized vegetable oil polymerized to a suitable viscosity for enhancing applicability to a net fabric with tackiness to cover and keep the anti-fouling agent in a homogeneously dispersed state and the resultant dispersion is then diluted with an organic solvent (e.g. xylene) to readily permeate and diffuse the anti-fouling agent in fine interstices between twists of the aforementioned net fabric. Thereby, the anti-fouling agent is homogeneously and firmly applied even to the interior of the net fabric. As a result, the anti-fouling agent is eluted for a long period without being washed with waves, etc., to prevent trouble of marine microorganisms. Furthermore, linseed oil is preferred as the vegetable oil.

The fine grinding condition is that the working pressure, the working time and the rotating speeds of the upper lapping machine and the lower lapping machine 5 are all designated values. The rotating speeds of the upper and lower lapping machines are reversed every time working is performed five times. The polishing condition is that the working pressure, the working time and the rotating speeds of the upper lapping machine and the lower lapping machine 5 are all designated values.  The rotating speeds of the upper and lower lapping machines are reversed every time working is performed five times. Thus, the flatness and surface roughness of a worked article can be kept and improved.
